condensation inside new windows

[hopful]

Hi I had 4 pvc windows installed in the spring and they all have condensation around the bottom now in the mornings. Is this normal or should I be calling the company back and requesting the fix it?

Call them back, definitely.

do you mean inside the unit, or do you mean on the room side, or do you mean on the outside?

Only internal condensation (inside the unit, between the panes) is a fault. You should have a 5-year guarantee on units.

Some days there is condensation on the outside which I believe (from mum)is how it should be.

But the last few days it has been on the room side around an inch or two from the bottom. Is that okay then? Mum thinks I should complain.

Ds2 room is worst and we don't dry washing in his room.

If it is on the room side, and not between the panes, it is not a fault.

It sounds like DS is breathing during the night, which will increase humidity. If he won't stop, open the trickle vents (if you have them) and open the windows every morning after the bed covers have been thrown back, to air them.

If you are drying washing inside the house, the water vapour will diffuse into other rooms. It is lighter than air so will travel upwards into upstairs rooms. If you must drape washing indoors, put it in the bathroom and leave the extractor fan running to suck the moisture out. Door and window should both be closed. If the extractor is worn out and noisy, a new one is not expensive. A typical extractor will run for 50 hours on 12p worth of electricity.

Thanks for your replies. Yes ds2 does tend the breath in his sleep but usually does it in my bed from midnight onwards.

Our bathroom is tiny and doesn't have a fan. We dry most the washing on a maiden our room. I could just wipe the bottom of the widows in the mornings to prevent the seals going moldy? Would that be okay am I missing anything?

Opening the windows will be better than wiping them.

A dehumidifier made a huge difference for us, we have a large one that does the whole house. Washing dries faster, less mould in the bathroom, less condensation... It's great.

if you have no bathroom extractor, and drape wet washing around, your home is sadly going to be very humid and damp.

Is it owned or rented? Have you got a loft above the bathroom? Do the windows have trickle vents? Have you got an extractor or extracting cooker hood in the kitchen (not a recirculating hood, which is useless)?
